Web比如评估基因组特征，组装基因组，物种样品污染评估等。评估基因组特征(genome survey)包括评估基因组大小(size)，杂合度，重复序列比例等。 组装基因组. 组装基因组使用k-mer的目的主要是去除低频率的k-mer以提高组装结果准确性。 评估基因组大小(size) Web4 giu 2024 · Jellyfish, such as Chrysaora quinquecirrha, hold an important evolutionary position and have great ecological value. However, limited genomic resources are currently available for studying their basic genetic and development processes. Here, we de novo assembled the first high-quality reference genome of C. quinquecirrha, and successfully …
